Do you not see that ships sail in the sea by Allah's Grace that He may show you some of His Signs? Surely there are Signs in this for everyone who is steadfast, thankful. 31 When the waves cover them like shadows, they pray to God with sincerity in their religion, but when We bring them safely to land, only some of them follow the right path. No one rejects Our revelations except the treacherous ungrateful ones. 32 O mankind, fear your Lord and fear a Day when no father will avail his son, nor will a son avail his father at all. Indeed, the promise of Allah is truth, so let not the worldly life delude you and be not deceived about Allah by the Deceiver. 33 Allah, He alone has knowledge of the Hour. He sends down the rain and He knows what is in the wombs. No soul knows what he will earn tomorrow; and no soul knows in what land it will die. Surely, Allah is the Knower, the Aware. 34
